Soon, users could smell Twitter notifications

A futuristic system, Sensabubble, could alert you for Twitter notifications with little scented bubbles.

According to CNET, Sensabubble is a system that allows colors, text, and icons to be projected on bubbles that are filled with scented fog.

Sriram Subramanian, professor of human-computer Interaction in the University of Bristol Interaction and Graphics group has made a prototype of Sensabubble, for Twitter notifications, but the model is not portable.
